Question

What is the value of x in the solution to this system of equations?

5x+2y=67x=3y−7
Question 4 options:

6


18.5


24


11

Answer 1

x = 11

Explanation:

Given the expression;

5x+2y=67 ...1

x=3y−7 ....2

Substitute 2 into 1

5(3y-7)+2y = 67

15y - 35 + 2y = 67

17y = 67+35

17y = 102

y = 102/17

y =6

Recall that x = 3y - 7

x = 3(6) - 7

x = 18 - 7

x = 11

Hence the value of x is 11
