Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
multiply everything by 3 then add it all up
1.25×3= 3.75
2.5×3= 7.5
1×3=3
7.5+3.75+3= 14
Answer:
2/3
Step-by-step explanation:
Ratio means division, so it's 12/18 / 6/6 = 2/3
The error made was in step two because you do not add 1 and 48, you subtract. this would result in "no solution" since you can't find the square root of a negative number
