Answer:
Step-by-step explanation:
-3x - 4y = - 2 ----------------(i)
y = 2x - 5 -------------(ii)
substitute the value of y in equation(i)
-3x - 4*(2x - 5) = -2
-3x -4*2x -(-4)*5 = -2
-3x - 8x + 20 = -2
-11x + 20 = -2
-11x = -2 -20
-11x = -22
x = -22/-11
x= 2
Plug in the value of x in equation (ii)
y = 2*2 - 5
y = 4 - 5
y= -1
