Sagot :
Answer:
1) x=8
2) x=20
3) x=18
Step-by-step explanation:
1) divide both sides by 2 to cancel 2 from x.
2) subtract both sides of the equation by 10 to eliminate 10 from x.
3) add both sides of the equation by 6 to eliminate 6 from x.
Answer:
1.) 8
2.) 20
3.) 18
Step-by-step explanation:
1.)
[tex]2x = 16 \\ \frac{2x}{2} = \frac{16}{2} \\ x = 8[/tex]
2.)
[tex]x + 10 = 30 \\ x = 30 - 10 \\ x = 20[/tex]
3.)
[tex]x - 6 = 12 \\ x = 12 + 6 \\ x = 18[/tex]
