7x + 5
8x + 9
find the value of x so that both the sum of the equations equal 180 when added together.
both the sum of the equations ??
typo, i think it's just meant to say the sums of the equations
well, add them up and you have
15x+14 = 180
To find the value of x that satisfies the criteria, we need to equate the sum of the two equations to 180.
First, let's add the two equations together:
(7x + 5) + (8x + 9) = 180
Combine like terms:
15x + 14 = 180
Next, isolate the variable by subtracting 14 from both sides of the equation:
15x = 180 - 14
15x = 166
Finally, divide both sides of the equation by 15 to solve for x:
x = 166/15
The value of x that satisfies the criteria is approximately 11.067.
