Question

3(0,4+7)-4(0,8x-3) =2

Answer 1

3*(0,4x+7)-4(0,8x-3)=2
1.2х+21-3.2х+12=2
-2х=-31
х=15.5

Answer 2

To solve the equation 3(0.4+7)-4(0.8x-3) = 2, follow these steps:

Step 1: Simplify the expressions within the parentheses: 3(4+7) - 4(8x-3) = 2

Step 2: Perform the operations within the parentheses: 3(11) - 4(8x-3) = 2

Step 3: Continue simplifying by applying the distributive property: 33 - 32x + 12 = 2

Step 4: Combine like terms: 45 - 32x = 2

Step 5: Isolate the variable term (in this case, -32x) on one side of the equation: -32x = 2 - 45

Step 6: Simplify the right-hand side: -32x = -43

Step 7: Solve for x by dividing both sides by -32: x = -43 / -32

Step 8: Simplify the fraction: x = 43/32

So, the solution for the equation is x = 43/32.
