Problem

Find the value of x for this system.

Equation A: 4x + 3y = −14

Equation B: y = 2

4x + 3y = −14

y = 2

The problem asks to solve for x. Equation B gives you the value of y, y = 2, so you can substitute 2 into Equation A for y.

4x + 3(2) = −14

Substituting y = 2 into

Equation A.

4x + 6 = −14

4x = −20

x = −5

Simplify and solve the equation for x.

Answer

x = −5
