10 × 2 tens = 20 tens = 200
First, multiply the second equation by 4 so that 8y can cancel out. Now you have
5x+8y=-29
and
28x-8y=-268
Add these equations to get
33x=-297
Divide both sides by 33, and you have
x=-9
Now, simply solve for y by plugging it into an equation, and you have
y=2
The final answer is (-9,2)!
Answer:
y=-2x+2
Explanations:
the slope is -2 and the y-intercept is (0,2)
a raise to m ∙ a raise to n = a raise to (m + n)
so 7 raise to (3+4)=7 raise to &
