Question

5*х+40=77+3, 100-24/а=92

Answer 1

1. х×5+40=77+3

5х+40=80

5х=80-40

5х=40

х=40:5

х=8

2. 100-24/а=92

100-92= 24/а

24:а=8

а=24:8

а=3

Answer 2

It seems like you have a system of two equations with two variables, x and a. Let's solve it step by step:

Equation 1: 5*x + 40 = 77 + 3

First, simplify the right side:

5*x + 40 = 80

Now, subtract 40 from both sides:

5*x = 40

Divide both sides by 5:

x = 8

Equation 2: 100 - 24/a = 92

First, subtract 100 from both sides:

-24/a = -8

Now, multiply both sides by -a to solve for "a":

-24 = -8a

Divide both sides by -8:

a = 3

So, the solutions to the system of equations are: x = 8 a = 3
