Answer:
x=10
Step-by-step explanation:
1) combine ALL like terms
5x-4+5x-4+3x+58=180
5x+5x+3x=13x
-4-4+58=50
13x+50=180
2) subtract both sides by 50
13x+50-50=180-50
13x=130
divide both sides by "13"
x=10
Hope this Helps!
Answer:
Step-by-step explanation:
Let x be the number of pants and y be the number of shirts
x + y = 6
20x + 15y = 100
multiply the first equation by -20
-20x -20y = -120
20x + 15y = 100
subtract the equations
-5y = -20
y = 4
replace y in equation 1
x + 4 = 6
x = 2
