3x-2y=7
-x+3y=-7
What is the simultaneous answer?
​

x = 5, Y = 4

Step-by-step explanation:

3x -2y = 7

-3x +9y = 21. (multiple the whole thing by 3 to get the xs to cancel)

7y = 28

y = 4

substitute y to find x

3x - 2(4) = 7

3x -8 = 7

3x = 15

x = 5

for b its (t) and c its (d)

step-by-step explanation:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
