  • 3² - 4/2 × 3 - 4 = 9 - 4/2
  • 5/2

[2] 4 - 3x/2x + 4

  • 4 - 3 × 2/2 × 2 + 4 = 2/8
  • 1/4

[3] x²/2x² - 2

  • 0²/2 × 0² - 2
  • 0

[4] x² + 5/5 - x

  • - 2² + 5/5 + 2 = 4 + 5/7
  • 9/7

[5] - x³/x² - 4

  • - 1³/-1² - 4 = - 1/1 - 4
  • 1/3

[6] x + 3/x³ - 1

  • - 3 + 3/- 3³ - 1 = 0/- 27 - 1

Math help what is the answer will give brainliest.
artcher [175]
The two equations are
x + y = 7
and
4x + 2.5y = 22
the first equation can be solved for x to be
x = 7 - y
next you can substitute x in the second equation
4(7 - y) + 2.5y = 22
Distribute 4 to everything in the parentheses
28 - 4y + 2.5y = 22
combine like terms:
28 - 1.5y = 22
subtract 28 from both sides of the equation
- 1.5y =  - 6
divide both sides by -1.5
y =  4
plug this in to the original equation of x+y=7
x + 4 = 7
subtract 4 from both sides.
x = 3
