.04(2x)+.03(x)+.05(500+x)=2025

.08x+.03x+.05x+25=2025

.16x+25=2025

.16x=2000

x=12500

She has 2x invested at 4%, so she had $25000.00 invested at 4%.

What is the solution of the system? 7x+5y=19 and -7x-2y=-16 Need help ASAP
Stells [14]

Answer:

x = 2, y = 1

Step-by-step explanation:

  • 7x + 5y = 19
  • -7x - 2y = -16

Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.

0 + 3y = 3

Divide both sides by 3.

y = 1

Substitute 1 for y into the first equation.

7x + 5(1) = 19

7x + 5 = 19

Subtract 5 from both sides.

7x = 14

Divide both sides by 7.

x = 2

Please help me step by step thanks
Gemiola [76]
Left:
180-53 = (8x-9)
127+9 = 8x
136 = 8x
x = 17
Right:
(15x+29) = (26x-4)
29+4 = 26x-15x
33 = 11x
x = 3
