Solve the linear equation.<br> 7x+10= 1/3(12x-3)+14x

pychu [463]

7x+10=1/3×(12x-3)+14x

7x+10=1/3×3(4x-1)+14x

7x+10=(4x-1)+14x

7x+10=4x-1+14x

7x+10=18x-1

7x-18x=-1-10

-11x=-11

x=1

Drag the tiles to the correct boxes to complete the pairs. Add each pair of monomials and match it to the correct sum. -15u3 + 5

Grace [21]

Consider the given monomials. Let us determine the sum of these monomials,

1. $-15u^3+5u^3$

= $-10u^3$

Therefore, the sum of the given monomials is $-10u^3$ .

2. $10u^3+(-5u^3)$

= $10u^3-5u^3$

= $5u^3$

Therefore, the sum of the given monomials is $5u^3$ .

3. $10u^3+5u^3$

= $15u^3$

Therefore, the sum of the given monomials is $15u^3$ .

4. $5u^3+(-10u^3)$

= $5u^3-10u^3$

= $-5u^3$

Therefore, the sum of the given monomials is $-5u^3$ .
