Question

To determine whether

(-1,4) is a solution to the equation 3x + 8y =
29, substitute
for x —
and
for y — .

Answer 1

(- 1, 4 ) is a solution to the equation

Explanation:

Substitute x = - 1 and y = 4 into the left side of the equation and if the value obtained is equal to the right side then it is a solution

Given

3x + 8y = 29, then

3(- 1) + 8(4) = - 3 + 32 = 29 = right side

Thus (- 1, 4 ) is a solution of the equation
