Answer:

The solution is -22

Step-by-step explanation:

<em>The solution of an equation is the value of the variable of the equation</em>

∵ -(4x - 3) = -7(9 + x)

→ Simplify each side

∵ -(4x) - -(3) = -7(9) + -7(x)

∴ (-4x) - (-3) = -63 + (-7x)

→ Remember (-)(-) = (+) and (-)(+) = (-)

∴ -4x + 3 = -63 - 7x

→ Add 7x to both sides

∴ -4x + 7x + 3 = -63 - 7x + 7x

∴ 3x + 3 = -63

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = -63 - 3

∴ 3x = -66

→ Divide both sides by 3

∴ x = -22

∴ The solution is -22

Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

$\frac{7}{90} = \frac{x}{140}$

cross multiply

$7 *140$ $= 980$

divide the answer by 90 to find x

$980/90= 10.8$

round to 11 because you can't have 10.8 bottles
