Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x

How do i solve 1/2 × 3/7how do I solve one third of 3/7 <br><img src="https://tex.z-dn.net/?f=%201.5%20%5Ctimes%203.7" id="TexFo

1) $\frac{1}{2}\,X\,\frac{3}{7}$ = $\frac{3}{14}$

2) $\frac{1}{3}\,X\,\frac{3}{7}$ = $\frac{1}{7}$

3) $1.5 \times 3.7\\$ = $5.55$

Step-by-step explanation:

We need to solve following expressions.

1) $\frac{1}{2}\,X\,\frac{3}{7}$

We need to multiply numerator with numerator and denominator with denominator

Solving:

$\frac{1}{2}\,X\,\frac{3}{7}\\=\frac{3\,X\,1}{2\,X\,7}\\=\frac{3}{14}$

It cannot be further simplified so, $\frac{1}{2}\,X\,\frac{3}{7}$ = $\frac{3}{14}$

2) one third of 3/7

one third stands for 1/3

Now solving:

$\frac{1}{3}\,X\,\frac{3}{7}$

We need to multiply numerator with numerator and denominator with denominator

$\frac{1}{3}\,X\,\frac{3}{7}\\=\frac{3\,X\,1}{3\,X\,7}\\=\frac{3}{21}\\=\frac{1}{7}$

It cannot be further simplified so, $\frac{1}{3}\,X\,\frac{3}{7}$ = $\frac{1}{7}$

3) $1.5 \times 3.7\\$

In this question we have to multiply 1.5 with 3.7

$1.5 \times 3.7\\=5.55$

So, $1.5 \times 3.7\\$ = $5.55$
