Answer:
x = 14/3
y = 16.3333333333
Step-by-step explanation:
Step 1. equal them to each other and solve for x
2x + 7 = 5x - 7
5x - 2x = -14
3x = 14
x = 14/3
Step 2. Plug in the value of x and solve for y
y = 5x - 7
y = 16.3333333333
tadah!
Answer:
x= 14/3
y= 49/3
Step-by-step explanation:
y= 2x+7
y= 5x-7
-2x + y = +7
(-5x + y = -7) * (-1)
-2x + y = +7
+5x - y = +7
3x +0y= 14
3x= 14
x= 14/3
replace x in any equation from these 2:
y= 2x+7
y= 5x-7
ill chose this :
y= 2x+7
y= 2(14/3) +7
y= 49/3
