For the given system of equation, the value of x = 4 and the value of y = -1
Solving simultaneous equations
From the question, we are to solve the given system of equations
-7x + 4y = -32 -------- (1)
9x - 2y = 38 -------- (2)
From equation (2)
9x - 2y = 38
2y = 9x - 38
y = 4.5x - 19 -------- (3)
Substitute this into equation (1)
-7x + 4y = -32
-7x + 4(4.5x -19) = -32
-7x + 18x - 76 = -32
-7x + 18x = -32 + 76
11x = 44
x = 44/11
x = 4
Substitute the value of x into equation (3)
y = 4.5x - 19
y = 4.5(4) - 19
y = 18 - 19
y = -1
Hence, the value of x = 4 and the value of y = -1
