Find the number of marbles in John's collections.

Answer 1

Answer: John has 52 marbles in his collection

Explanation:

Step 1

LET The number of marbles in John's collection can be represented by x. The and the number of marbles in Erica collection can be represented as =4x+ 10

The total number of marbles in both collections is 270 such that the expression to solve the equation will be

JOHN + ERICA = 270marbles

X + 4X+ 10= 270

Step 2--- solving

X + 4X+ 10= 270

5X+ 10= 270

5X= 270-10

5X= 260

X= 260/5

=52

John has 52 marbles in his collection

Erica has 4x + 10 = 4x 52 + 10=218 marbles
