Answer: a. x=4 b. x=17.5
Step-by-step explanation:
a. 5x/2+1=11
subtract 1 from both sides : 5x/2=10
multiply both sides by 2 : 5x=20
divide both sides by 4 : x=4
b. 2x/7-3=2
add 3 to both sides : 2x/7=5
multiply both sides by 7 : 2x=35
divide both sides by 2 : x=17.5
Answer:
infinite
Step-by-step explanation:
If you multiply all factors in the secon eqation by 4, you will get the first eqation.

Answer:
idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want
Step-by-step explanation:
Let's solve for x.
6x+7y=13x
Step 1: Add -13x to both sides.
6x+7y+−13x=13x+−13x
−7x+7y=0
Step 2: Add -7y to both sides.
−7x+7y+−7y=0+−7y
−7x=−7y
Step 3: Divide both sides by -7.
−7x
−7
=
−7y
−7
x=y
Answer: $18 dollars left
Step-by-step explanation:
