Question

Solve the system of equations.
y=8x-11
y=x+17

Answer 1

Answer: See below

Explanation:

y = 8x - 11
y = x + 17

We can solve this with substitution method:

8x - 11 = y = x + 17

Thus, 8x - 11 = x + 17 ( they both = y )

8x - 11 = x + 17
8x - x = 17 + 11
7x = 28
x = 4

Substitute x value to find y:

y = 8(4) - 11
y = 32 - 11
y = 21

Therefore, x = 4 and y = 21

Answer 2

Answer:

This is a simultaneous equation

Step-by-step explanation:$1-y=8x2-y=x+17Multiply equation 2 with -8 so that you can cancel out both 8y=8x-8y=-8x-1361y-8y=-7y+8x and -8x will cancel outso the equation is-7y=-136y=-136\frac{x}{y} -7y=19.428put the value of y in equation 119.428=8x19.428\frac{x}{y} 8=xso x=2.4285good luck$
