answer:
x = 0.80
y = 1.50
step-by-step explanation:
x = cost of tacos
y = cost of burritos
both equations:
3x + 2y = 5.40
2x + 1y = 3.10
^
turn this | into this |
v
y = 3.10 - 2x
then add it to the equation :
3x + 2 [ 3.10 - 2x ] = 5.40
3x + 6.2 - 4x = 5.40
-1x = - 0.8
x= 0.80
then add x = 0.80 to the equations to get :
3 [ 0.80 ] + 2y = 5.40
2.4 + 2y = 5.40
2y = 3
y = 1.5
Answer:
x=2
Step-by-step explanation:
5×2=10-2=8
You subtract add two to both sides, giving you 5x=10
Divide the 10 by 5 and you get 2.

Answer:
x = 2, x = -8
Step-by-step explanation:
Since the equation equals 0, you know either (x-2) or (x+8) has to equal 0.
This means x = 2, and x = -8
