Answer:
Step-by-step explanation:
It would be answer b, because if you were to solve this, then this is how you would do it (in the most effecient way):
2.5x + 1.2 = 1.2x + 4.2
2.5x + 1.2 - 1.2 = 1.2x + 4.2 - 1.2
2.5x = 1.2x + 3
2.5x - 1.2x = 1.2x - 1.2x + 3
1.3x = 3
1.3x/1.3 = 3/1.3
x = 3/1.3
x=4
4x-3=5x-7
-1x-3=-7 Subtract the 5x on both sides
-1x=-4 Add the -3 to the -7
27 /20 =1 and 7 over 20= 1.35
Is the anser suppose to be the numbers that equal 180?
