Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
129,407 because 12 ten thousands is 120,000 and 8 thousands is 8,000. 14 hundreds is 1,400 and 7 ones is 7 so 120,000+8,000+1,400+7=129,407
300-90= 90-90 +0.11x 210=0.11x 210/.11 0.11x/0.11
1909 = x I think but Idk
B is the answer because 1+3 is 4 4+5 is 9 9+7 is 16 16+9 is 25 25+11 is 36+13 is 49 and so on
x+19= 26
x+19-19= 26-19
x= 7
Check answer by using substitution method
x+19= 26
7+19= 26
26= 26
Answer is x= 7 (D.)
