Answer:

x=-5

Step-by-step explanation:

4-2(x+7) = 3(x+5)

distribute:

4-2x-14=3x+15

combine like terms:

-10-2x=3x+15

subtract 3x from both sides:

-10-5x=15

ADD 10 from both sides to cancel out -10:

-5x=25

Divide -5 from both sides to cancel out the variable:

Answer: x= −5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−2(x+7)=3(x+5)

4 + (−2)(x)+(−2)(7) = (3)(x)+ (3)(5) (Distribute)

4+−2x + −14= 3x+ 15

(−2x)+(4+−14)=3x+15(Combine Like Terms)

−2x + −10= 3x+15

−2x−10=3x+15

Step 2: Subtract 3x from both sides.

−2x−10−3x=3x+15−3x

−5x−10=15

Step 3: Add 10 to both sides.

−5x−10+10=15+10

−5x=25

Step 4: Divide both sides by -5.

−5x/−5 = 25/−5

x=−5

Bella and Heather put some money into their money boxes every week. The amount of money (y), in dollars, in their money boxes af
ss7ja [257]

ANSWER

10 weeks, $310


EXPLANATION

We have a system of linear equations as both equations need to be satisfied by the same ordered pair (x,y):


y = 25x + 60

y = 30x + 10


We can solve this by substitution. Since y is equal to 25x+60, we can substitute in 25x + 60 for y in the equation y=30x+10


y = 30x + 10

25x + 60 = 30x + 10


Subtract 25x from both sides


60 = 5x + 10

Subtract 10 from both sides and then divide both sides by 5


50 = 5x

x = 10


x represents time in weeks, so 10 weeks.


Find y, the amount of money, by substituting x=10 into either equation.

If we use y = 30x + 10, then


y = 30x + 10

y = 30(10) + 10

y = 300 + 10

y = 310


y = 310 implies $310 so the answer is 10 weeks, $310.
