Answer:
Dennis's score = 104
Step-by-step explanation:
Let us represent:
Dennis's score = x
Amanda's score = y
Jorge's score = z
Three friends go bowling.​
Dennis's score is 46 points greater than​ Amanda's score.
x = 46 + y
​ Amanda's score is 70 points less than​ Jorge's score.
y = z - 70
If​ Jorge's score is​ 128
z = 128
what is​ Dennis' score?
Step 1
we solve for y = Amanda's score
y = z - 70
z = 128
y = 128 - 70
y = 58
Step 2
We solve for Dennis's score
x = 46 + y
x = 46 + 58
x = 104
Dennis's score = 104
