Answer:
Ya gotta share
Step-by-step explanation:
3 (x + 2) + 4(x - 5) = 10
Simplify.
3x + 6 + 4x - 20 = 10
Add like terms.
(3x+4x) + (6-20) = 10
Simplify.
7x - 14 = 10
Add 14 to both sides of the equation.
7x = 24
Divide both sides by 7 so that X is by itself.
x = 24/7, or 3 3/7
~Hope I helped!~
Expression: 80+15x=y
(x means months)
so at the end of the year jason will have $260
3/7x + 4 = -1/2
subtract 4 from both sides
3/7x= -1/2 - 4
3/7x= -4 1/2
divide both sides by 3/7
x= -4 1/2 ÷ 3/7
convert -4 1/2 to improper fraction
x= (-4*1+1)/2 ÷ 3/7
x= -9/2 ÷ 3/7
multiply by reciprocal of 3/7
x= -9/2 * 7/3
multiply numerators & denominators
x= (-9*7)/(2*3)
x= -63/6
x= -10 3/6
simplify 3/6 by 3
x= -10 1/2
CHECK:
3/7x + 4 = -1/2
3/7(-63/6) + 4= -1/2
(3*-63)/(7*6) + 4= -1/2
-189/42 + 4= -1/2
-4 1/2 + 4= -1/2
-1/2= -1/2
ANSWER: x= -63/6 or -10 1/2
Hope this helps! :)
