Question

8x+3y= 70; y=2 Solve for x.

Answer 1

Explanation

• Given the equation.

$8x + 3y = 70$

with given condition where y = 2.

Therefore, substitute the value of y in the equation.

$8x + 3(2) = 70 \\ 8x + 6 = 70$

• Solve the equation for x-term.

$8x = 70 - 6 \\ 8x = 64 \\ x = \frac{64}{8} \longrightarrow \frac{8}{1} \\ x = 8$

• Answer Check by substituting the value of y and x in the equation.

$8x + 3y = 70 \\ 8(8) + 3(2) = 70 \\ 64 + 6 = 70 \\ 70 = 70$

Hence, the equation is true for x = 8 and y = 2.
