Question

3х-1=2(х-2) 3(х+5)=7-5х 19(у-9)=3(у+7) 4(х-9)=3(х-8) 3(2х-9)=5(х-4) 7(3-2х) =15(1-х)

Answer 1

3х-2х=-4+1
х=-3

3х+15=7-5х
8х=-8
х=+1

19у-171=3у+21
16у=192
у=12

4х-36=3х-24
х=12

6х-27=5х-20
х=7

21-14х=15-15х
х=-6

Answer 2

3х-1=2(х-2)  
3х-1=2х-4
3х-2х=-4+1
х=-3

3(х+5)=7-5х 
3х+15=7-5х
3х+5х=-15+7
8х=-8
х=-1

19(у-9)=3(у+7) 
19у-171=3у+21
16у=192
у=12

4(х-9)=3(х-8) 
4х-36=3х-24
4х-3х=36-24
х=8

3(2х-9)=5(х-4) 
6х-27=5х-20
х=7

7(3-2х) =15(1-х)
21-14х=15-15х
х=-6

Answer 3

I can help you solve linear equations using different methods. Here are some steps to follow:

- First, simplify each equation by distributing any coefficients and combining any like terms. - Second, choose a method to eliminate one of the variables from two equations. You can use substitution, elimination, or cross multiplication. - Third, solve for the remaining variable in the new equation. - Fourth, substitute the value of the variable into one of the original equations and solve for the other variable. - Fifth, check your solution by plugging the values of the variables into all the equations and verifying that they are true.

For example, to solve the first equation 3x - 1 = 2(x - 2), you can use the following steps:

- Simplify the equation by distributing the 2 and subtracting x from both sides: 2x - 1 = -4 - Add 1 to both sides and divide by 2: x = -3/2 - Substitute the value of x into the original equation and solve for y: 3(-3/2) - 1 = 2(-3/2 - 2) - Simplify and solve for y: -9/2 - 1 = -3 - 4 - Add 9/2 to both sides and simplify: y = -1/2

You can use the same steps to solve the other equations. If you need more help, you can watch some videos or use some online tools that explain how to solve linear equations in detail. You can also use a calculator to check your answers. I hope this helps you. Have a nice day!solve linear equations
