Answer 1

$P) 7=x+8\to\\\\ 7-8=x\to\\\\ -1=x\to \\\\x=-1\\\\\\\\\\Q) 4x-1=3(x-1) \to \\\\4x-1=3x-3\to \\\\ 4x-3x=-3+1\to \\\\x=-2$





$R) 3(x-2)=2x-4\to \\\\ 3x-6=2x-4\to \\\\ 3x-2x=-4+6\to \\\\ x=2\\\\\\\\\\ S) 10-9x+2x=2-3x\to \\\\ -9x+2x+3x=2-10\to\\\\ -4x=-8(-1)\to 4x=8\to\\\\ x= \frac{8}{4} \to \\\\ x=2$
