Answer:
Step-by-step explanation:
-2 (-x +5y ) + 3 (2x - 6y)
Opening bracket
= 2x - 10y + 6x - 18y
= 8x - 28y
= 4(2x - 7y)
y= 63-11
y= 52
-2x-3y=-7
-2x-3(52)= -7
-2x-156= -7
move -156 to the other side
sign changes from -156 to +156
-2x-156+156= -7+156
-2x= -7+156
-2x= 149
divide both sides by -2 to get x by itself
-2x/-2= 149/-2
x=- 149/2
Answer:
(-149/2, 52)
Answer: (x, y) → (x + 5, y - 7)
<u>Step-by-step explanation:</u>
left and right affect the x-value
up and down affect the y-value
5 to the right means "add 5" to the x-value --> x → x + 5
7 down means "subtract 7" from the y-value --> y → y - 7
To solve, we need to know by how much y increase to know how much to increase x by:
First step, divide the new value, 36 by the original 24:
36/24 = 1.5
Now, multiply the 1.5 by the x to get the new increase value:
16 x 1.5 = 24
So, x= 24 when y= 36
Hope this helps!
