Answer:
Step-by-step explanation:
Let a = original amt in the savings account
"He spent $48 on a radio and 3/8 of what was left on presents for his friends."
Therefore he kept 5/8 of what was left
5/8(a - 48)
5/8(a - 30) left
:
John then put 2/3 of his remaining money into a checking account and donated the $100 that was left to charity.
a = 2/3(5/8a - 30) + 100
a = 5/12a - 20 + 100
a = 5/12a + 80
a - 5/12a = 80
7/12a = 80
a = $137.17 originally in his saving acct
Answer: Down 2, right 3
Step-by-step explanation:
Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.
<h3>Define equation.</h3>
A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.
Given,
Equation:
2x + y = 4
x - y = 2
From equation 2,
x = 2 + y
Equating in equation 1,
Using substitution method,
2(2+ y) + y = 4
4 + 2y + y = 4
3y = 0
y = 0
x = 2 + y
x = 2+ 0
x = 2
Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.
