10 buttons on a telephone key pad
Not enough information to solve
7y = 3y - 12 4y = -12 y = -3
x=5
5x^(2) = 11 Divide both saudes by 5' Hence x^(2) = 11/5 Square root both sides x = +/-sqrt (11/5) Or x = +/-sqrt(2.2) This would normally by left in 'surd' form, because the answer is an IRRATIONAL number; the decimals go to inifinity!!!!! However, per calculator x = +/- 1.483239697.....
how can i solvev 10=7-m
10
-2y = 10 2y = -10 y = -5
10 - 3 217 equals - 3 207.
A + 10 = 7.9Subtract 10 from each side:A = 7.9 - 10 = -2.1
5
a + 4 = 10(a + 4) - 4 = 10 - 4a = 6
1566 = x
