Question

solve : 3 X + 4 (x -1) = 10​

Answer 1

Answer:

3+4(−1)=10

3x+4(x-1)=103x+4(x−1)=10

Solve

1

Distribute

3+4(−1)=10

3x+{\color{#c92786}{4(x-1)}}=103x+4(x−1)=10

3+4−4=10

3x+{\color{#c92786}{4x-4}}=103x+4x−4=10

2

Combine like terms

3+4−4=10

{\color{#c92786}{3x}}+{\color{#c92786}{4x}}-4=103x+4x−4=10

7−4=10

{\color{#c92786}{7x}}-4=107x−4=10

3

Add 

4

44

 to both sides of the equation

7−4=10

7x-4=107x−4=10

7−4+4=10+4

7x-4+{\color{#c92786}{4}}=10+{\color{#c92786}{4}}7x−4+4=10+4

Simplify

Add the numbers

Add the numbers

7=14

7x=147x=14

5

Divide both sides of the equation by the same term

7=14

7x=147x=14

77=147

\frac{7x}{{\color{#c92786}{7}}}=\frac{14}{{\color{#c92786}{7}}}77x=714

Answer 2

Answer:

x=2 is the answer.

Step-by-step explanation:

3 X + 4 (x -1) = 10

3x+4x-4=10

7x-4=10

7x =10+4

7x= 14

x= 14/7

x=2
